19 Claims. (Cl. 298-18) This invention relates to side dump wagons and particularly to such wagons which are provided with gates which automatically open when the wagon is tilted to dump the load.

One of the objects of the invention is to provide an improved wagon of this type.

A further object of the invention is to provide a dumping wagon having an improved gate opening linkage operable to open a gate when the wagon is tilted in one direction and inoperative when the wagon is tilted in the opposite direction.

A further object of the invention is to provide a dump wagon having gates which automatically open to their fullest extent when the load is tilted f through a relatively small angle, for example an angle of the order of about 15 degrees.

A further object of the invention is to provide a dump wagon having linkages for automatically opening the gates when the wagon is tilted, which are inexpensive to construct, and which are simple, durable, and effective in operation.

Other objects, advantages and capabilities of the invention will appear from the following description of preferred embodiments thereof taken in conjunction with the accompanying drawings,

Fig. 7 is a side detail View thereof;

Fig. 8 is a sectional elevation taken on the line 8 8 of Fig. l, the linkages being omitted for the sake of clarity.

Fig. 9 is a sectional detail view taken on the line 9 9 of Fig. 8, and

Fig. l0 is a sectional plan detail view showing the means for locking the locking bar in one tilting position or the other.

Referring to the accompanying drawings, the reference numeral I I designates wheels which may suitably be of the track laying type. These wheels support the axle I2 upon which is mounted by brackets I3 the chassis or frame I4.

The chassis or frame I4 comprises two longitudinal channels |5 which converge at their forward ends. At their rear ends the channels |5 are connected by a transverse member or beam I6 which provides brackets |'I projecting outwardly beyond the channels I5. The channels |5 also support brackets I8 at the position of the forward end of the wagon body I9, which brackets project 5 into longitudinal alignment with the brackets I1. The wagon body I9 is mounted on channels 29 which are'adapted to rest upon the channels I5. The body comprises a. bottom 2| which rests on a sub-structure supported on the channels 20, l0 front and rear walls 22 and 23, and side gates 24 pivoted adjacent their lower edges on pivots 25, of which a suitable number are provided along the length of the gate. The gates 24, when opened, are adapted to abut upon the adjacent l5- portions of the body so that they lie in alignment with the bottom 2| as shown in Fig. 3.

` Each bracket |'I and I8 supports a socket member 26 which is provided with a longitudinal recess, in which is received a. longitudinal fulcrum 20 2l supported on webs 28 which depend from a bracket 29, one of which is secured to the underside of the body at each corner thereof so as to register with the socket members 26.

Above the position of the fulcrum 21 when it 25 is located in the longitudinal recess, each socket member is provided with openings in transverse alignment through which is adapted to pass a bar 3D. As will readily be seen from Figs. l and 8, a bar 39 cooperates with the socket members 30 26 carried by the brackets I'I and another bar 30 cooperates with the socket members 26 carried by the brackets I8. The bars 30 have a slot and pin connection with arms 3| which are rigidly mounted on a rod 32 rotatably supported upon 35 the chassis I4 and carrying a hand lever 33 at its forward end whereby the bars 30 may be thrown in one direction or the other transversely to free one or the other longitudinally aligned pair of fulcrums 21 as desired. 'I'he bars 30'are provided with stops 34 to limit the movement of said bars.

Means are preferably provided to lock the bars 39 in position after the body has started to tilt. Such means may comprise a bolt 35 which is slidably mounted in a housing 36, mounted on the frame adjacent one of the' bars 30. The bolt is retained in the housing by a collar 31 against which bears a spring 38 which normally forces the boit 35 upwarmy. Part of the bolt 35 under- 50 lies the bar 30 and is cut away to provide a shoulder 39. The remaining part 40 of the bolt projects above the bar 30 and is adapted to be depressed by the body I9 in its normal position, as shown in Fig, 9. .when the body is uned 55 about the fulcrum on one side or the other as determined by the position of the bars 30, the bolt 35 is forced upwardly by the spring 3B and the shoulder 39 passes through a slot 4l in the adjacent bar 35 and locks it against longitudinal movement until the bolt 35 is again depressed by the body I9 on its return to normal position. Two slots 4l are provided which register with the bolt 35 in the extreme positions of the bar 3i! which correspond with the locking of the 'fulcrums 21 on one side or the other.

Any suitable known means may be employed to tilt the body. I prefer to employ an'extensible ram 42 which is pivot-,ally connected at 43 at its upper end to the sub-structure of the body .and at 44 at its lower end to a transverse member Y45 carried between the main channels I5 of the chassis i4.

In operating the vehicle to dump itsload, the hand lever 35 is thrown in the direction' in which it is desired .to dump'the;load,for;.example=to the left as viewed inrFig. 8. 'The resulting movement of the bars 3`locks'the fulcrumsi'21zonthe left handsid-e in their socket members 'Zt'and leaves a free path for .the fulcrums 21on the right hand side so that they-mayfliftvertically out of their socket members 25. This 'movement also bringsl one of the slots -4I into vertical alignment with the'bolt 35 which is at this time held in its lowest position'byitscontact with 4the body I9. Pressure uid, derived :from a vtractor'or other suitable source-is admitted intotheram 42 causing it to expand itand elevate the body about the left hand fulcrums 21. The ram-42 may be adapted to'elevate the body through a suitable angle, for example l55 or 60 degrees. Whenthe body starts to rise the shoulder 350i the bolt'35 passes through the aligned slot 4 I. and locks thebars S35 against movementfuntil the body returns;toits'normalposition and depresses the bolt 35.

VvMeans areprovided for opening the gate 24 on the dumping sideof Vthe-body when the tilting movement is'in its finitialstage. Such ymeans will now be described.

Referring to-Figs. l'to 4 inclusive, it will be seen that adjacent each end, each gate 24-is provided with `av downwardly :projecting bracket `46 which is jpivotally-connected at 41`to1-a linkf48 which extends inwardly between the body .and the chassis, :The :inner =.end of fthe J link :48 is forked and is 'pivotally'connectedfat-49 tothe forked end of a shorter link 50which is-pivotally connected at 5| to'brackets 52 mounted-on the brackets vlEl or iii-as the'case" may be. The common pivots of thellinks-48` and 50 carry rollers 53 which -are kadapted tobear against-plates 54 carried on the'underside-.of the'bod-y-IS. The pivots 5i of the links 5!! are in: alignment or-substantial. alignment with the fulcrums 21,- the pivot 5l of-each linkagebeingzlocatedat the opposite side of the frame from the gate with which that linkage is connected.

It will readilybe' understoodfromFigsrZ- and 3 that-if the fulcrums 21 on theileft handside of the wagon, as viewed-inetheselgures,are locked in the manner--above-described and the'ram42 is extended, lthe plate 54 -rises and -the :roller tit-follows it, '.beingapressed*upwardly by the weight of thegate 24-onthe left -hand sideand the 4pressure of the -load 'thereagainst LIt will readily 'be-seen from .'Fig. 2 -thatin normal position fthe Vlinks 48 and 5l] lie kata relatively obtuse angle, so located that the -roller Y53 tends to move upwardly whenpermitted todo so by the plate 54. The relative lengths of the arm 46, link 48 and link 50 are such that the gate 24 opens rapidly, it being preferred that the gate should be fully open, that is in alignment with the floor 2| of the body when the body has 5 been tilted through an angle of about 15 degrees. As indicated above, the gate now abuts on the body and maintains this position relative to the body during the rest of the upward tilting movement, which may be considerable, for 10 example approximately 55 or 60 degrees. When the gate has become fully open or shortly thereafter,.the plate 54 moves upwardly away from the roller 53 and the linkage 48, 55 is free to adjust itself in position dictated by the move- 15 ment of the pivot- 41.

When the ram 42 is permitted to collapse the body i9 moves toward its initial position until the plate 54 contacts with the roller 53. This occurs when the body has arrived at a position 20 displaced-from its normal position by about`15 degrees. Further downward movement of the body forces the roller V53 Vdownwardly andinwardly so that the pivot 41 ofthe gate 24 receives an outward thrust which .closes the gate, the 25 gate being completely closed-when the body has resumed its'initial position.

-It will-be noted that during thedumpng movement to the left and the return movement of the body above described the right hand gate is 30 unaiected. This results from the factthat the pivot 5| of the linkage associated with the right hand gateiis` in alignment with the fulcrums 21 about'which thebody is'turning. Therefore, no

relativemovement occurs between the links 48, 35'

50 associated with the right hand gate and it remainsin its 'initial position, relative to the body, throughout the dumping operation. AOwing to the slight displacement of the links 48 and 50 out of alignment, in theirnormal position, it 40..

tive movement of the pivot 49 of the active 50` linkage, along the plate 54, causes the pivot 49 to clear the lug 56. On theother'hand, the lug 56 which underliesthe pivot '49 of the inactive -linkage remains beneath the projecting end of said pivot and prevents the linkage from 55 falling downwardly.

vAs will be seen from Figs. 1 and 4, the links 48 and 5i! may suitably Vbev located beneath the body I9 and on the inner side Vof the adjacent fulcrums 21. 'Ihis construction is particularly 60 advantageous since the linkages are thus preserved from accidental damage or destruction. As shown in Fig. 5 the construction may be modified so as to locate the linkages outwardly beyond the ends of the wagon body and the 60 fulcrums 21 and associated parts, the gates 24 being extended beyond the end walls 22 and 23 so as to locatethe 'brackets VIt in Ycorresponding position.

In the embodiment ofthe invention illustrated in Figs. 6and` 7,'wagon construction is substantially the saine as that in the embodiment previouslyfdescribed with'theexception of the linkage and similar reference numerals are employed to designate similar parts. 70

1n this embodiment each gate 24 is provided at each end with an inwardly directed ange 0r web 51 to which is pivotally attached, at a point above the pivots of the gate, a link 58 which extends transversely across the end walls of the wagon body, its remote end normally occupying a position in alignment with the fulcrums 21 on the other side of the Wagon from the gate 24 to which it is attached. This end of the link 58 is pivoted at 59 to a shorter link 60 which extends inwardly and is pivoted to the frame or chassis I4 adjacent its center. The link 60 may, for example be pivoted at 6I to an angle iron 62 mounted on a. transverse member or beam I6 or other suitable part of the chassis. The pivot 59 carries a roller 63 which is normally engaged by the flange 64 of an angle iron 65 mounted on the end wall of the body.

As seen in full lines in Fig. 6 the relation of the links 58 and 60 is such that the gate 24 is closed by the force exerted by the ange 64 upon the roller 59. When the body is tilted, for example toward the left as viewed in Fig. 6, the flange 64 on the right hand side of the body elevates and the link 6B is free to rotate around its pivot 6I so that the roller 63 moves upwardly and to the left along the flange 64. The gate 24 opens under the action of its weight and the weight of the load thereagainst. The relation of the linkage is such that the gate opens to its fullest extent when the body is elevated through a relatively small angle, for example an angle of 15 degrees and at that time the flange 64 moves upwardly away from the roller 63 which thereafter moves in the air to a slight extent only in accordance with the change of position of the link 58 with the gate 24, as the body moves to its full tilt, for example through an angle of 55 or 60 degrees.

When the body is allowed to return to its normal position the flange 64 re-engages the roller 63 and returns the linkage to the position shownv in full lines in Fig. 6, closing the gate 24. During the dumping operation just described the gate on the right hand side and the link 58 connected thereto do not move relatively to the body. Said link 58 pivots around the pivot 59, which is in line with the fulcrurns 21 about which the body moves during said dumping operation.
